Seventeen years ago, Jiangcheng in the south was a family area of a state-owned textile factory. Seventeen-year-old girl Liu Tingting died tragically late at night. The case was hastily closed and became an unresolved case. Seventeen years later, on the same day, three young girls mysteriously disappeared in the same area. All clues vaguely pointed to that dusty old case.
Lao Zhou, a retired criminal policeman, is suffering from illness and cannot let go of his obsession; Qin Yue, a young community worker, is eager to uncover the truth with her passion. In the process of investigating the girl's disappearance, this temporary partner of an old man and a young man gradually uncovered a cruel truth that has been sealed by time.
They found that every step in front of them seemed to be guided by a pair of invisible hands. The strange appearance of Lycoris Flowers, the precise provocation of anonymous phone calls, the ritual crimes committed by the real murderer... All of this stems from a desperate revenge that spans seventeen years. Who died that year? Who is coming back now? When the law loses its voice, the victim can only turn into an avenger and seek justice for himself in the most extreme way.
This is a well-planned death game and a cruel torture of human nature and justice. When the final truth is revealed, everyone will face a heavy question: when justice is delayed for seventeen years, is revenge for crime a sin, or is it destruction in another sense?
